The Priority Date of a Patent

A multilateral treaty known as the “Paris Convention”, to which most industrialized countries of the world are party, ensures that the filing date of an application in one member state is preserved in subsequent applications for the same invention in other member states, provided they are filed within one year of the original application date.

Preserving an early, original filing date in subsequent applications guarantees their priority over patent applications filed in that country after the original filing date by other inventors for the same invention. It also guarantees against rejection of subsequent applications due to publication or public disclosure of the invention released by the inventor or anybody else after the original filing date as you can see from this article – https://www.fingerlakes1.com/2022/02/08/how-to-patent-a-product-with-inventhelp/.

An applicant must request recognition of his or her first filing date in subsequent applications for the same invention, and provide details of the original application. The filing date of the original application is called a “priority date”.

The subject matter claimed in an application must form a single general inventive concept. Different aspects of an invention may be defined, of course, but there must be some technical relationship linking them. Disparate subject matters, unconnected in design or operation are not allowed in a single patent application. Claims of different categories, such as a claim to an article of manufacture and a claim to the process of manufacturing it, are allowed in one application as seen on how do you patent an idea with InventHelp post.
